Southern California's electricity system will be challenged this summer, and power emergencies may result if an extended drought leads to massive wildfires, the main U.S. electricity reliability watchdog said.

Southern California is the area that most concerns analysts at the North American Electric Reliability Corp (NERC), which issued its summer 2008 outlook recently.

Of Southern California, NERC said, "capacity margins will remain tight. Significant amounts of imported power are required to fortify capacity margins and preserve reliability, resulting in heavily loaded transmission lines into this area during peak conditions.

"As a result, unplanned major transmission or generation outages, or extreme temperatures/demand may lead to resource constraints."

NERC, of Princeton, New Jersey, is responsible for monitoring the reliability of the power grid in the United States, Canada and parts of Mexico.

NERC said voluntary conservation and on-call interruptible loads will likely be necessary more often than usual this summer.

As always, the biggest factor in how much demand will strain the power grids in California and the United States is the weather.

NERC said nationwide, U.S. temperatures were 12 percent warmer than normal in 2007 and 10 percent warmer than normal in 2006.

Last October, wildfires in San Diego County threatened a major transmission line and caused it to go off-line as the San Diego area nearly averted a power crisis, More wildfires could exacerbate an already precarious situation in California this summer, NERC said.

"Drought conditions persisting in Southern California, Nevada, eastern New Mexico and western Texas currently appear to have no impact on reliability, though potential for wildfires as a result of dry conditions can threaten infrastructure and will be monitored throughout the summer months," said the NERC study.

The California Independent System Operator, manager of the power grid on which flows 80 percent of the state's electricity, forecast a summertime peak demand of 49,071 megawatts, NERC noted.

The all-time peak demand in California was reached in July 2006 at 50,270 megawatts.

Cal ISO also saw a 1-in-10 chance that hot weather will increase that peak load forecast by 3,000 megawatts, thus reducing the capacity margin to less than 10 percent without additional power purchases.

Cal ISO spokeswoman Stephanie McCorkle said the grid manager agrees with the NERC assessment that the system needs to be under a careful watch this summer for Southern California. But she said it would take an unlikely confluence of events to create blackouts.

That would mean unexpectedly low imported power from outside California, high generation and/or transmission outages on a hot day, McCorkle said.

"We have more tools in our toolbox than we have had," said Cal ISO "We have more demand-response to tap now," said McCorkle, referring to customers that voluntarily cut use at times of high demand, often in turn for lower power rates.

In addition to high-use business customers, many residential customers have signed to have thermostats monitored remotely.

Global Energy War Escalates: Price Hikes and Instability

Russia-Ukraine Energy War disrupts infrastructure, oil, gas, and electricity, triggering supply shocks, price spikes, and inflation. Global markets face volatility, import risks, and cybersecurity threats, underscoring energy security, grid resilience, and diversified supply.

 

Key Points

It is Russia's strategic targeting of Ukraine's energy system to disrupt supplies, raise prices, and hit global markets.

✅ Attacks weaponize energy to strain Ukraine and allies

✅ Supply shocks risk oil, gas, and electricity price spikes

✅ Urgent need for cybersecurity, grid resilience, diversification

 

Russia's targeting of Ukraine's energy infrastructure has unleashed an "energy war" that could lead to widespread price increases, supply disruptions, and ripple effects throughout the global energy market, felt across the continent, with warnings of Europe's energy nightmare taking shape.

This highlights the unprecedented scale and severity of the attacks on Ukrainian energy infrastructure. These attacks have disrupted power supplies, prompting increased electricity imports to keep the lights on, hindered oil and gas production, and damaged refineries, impacting Ukraine and the broader global energy system.


Energy as a Weapon

Experts claim that Russia's deliberate attacks on Ukraine's energy infrastructure represent a strategic escalation, amid energy ceasefire violations alleged by both sides, demonstrating the Kremlin's willingness to weaponize energy as part of its war effort. By crippling Ukraine's energy system, Russia aims to destabilize the country, inflict suffering on civilians, and undermine Western support for Ukraine.


Impacts on Global Oil and Gas Markets

The ongoing attacks on Ukraine's energy infrastructure could significantly impact global oil and gas markets, leading to supply shortages and dramatic price increases, even as European gas prices briefly returned to pre-war levels earlier this year, underscoring extreme volatility. Ukraine's oil and gas production, while not massive in global terms, is still significant, and its disruption feeds into existing anxieties about global energy supplies already affected by the war.


Ripple Effects Beyond Ukraine

The impacts of the "energy war" won't be limited to Ukraine or its immediate neighbours. Price increases for oil, gas, and electricity are expected worldwide, further fueling inflation and exacerbating the global cost of living crisis.  Additionally, supply disruptions could disproportionately affect developing nations and regions heavily dependent on energy imports, making targeted energy security support to Ukraine and other vulnerable importers vital.


Vulnerability of Energy Infrastructure

The attacks on Ukraine highlight the vulnerability of critical energy infrastructure worldwide, as the country prepares for winter under persistent threats. The potential for other state or non-state actors to use similar tactics raises concerns about security and long-term stability in the global energy sector.


Strengthening Resilience

Experts emphasize the urgent need for global cooperation in strengthening the resilience of energy infrastructure. Investments in cybersecurity, diverse energy sources, and decentralized grids are crucial for mitigating the risks of future attacks, with some arguing that stepping away from fossil fuels would improve US energy security over time. International cooperation will be key in identifying vulnerable areas and providing aid to nations whose infrastructure is under threat.


The Unpredictable Future of Energy

The "energy war" unleashed by Russia has injected a new level of uncertainty into the global energy market. In addition to short-term price fluctuations and supply issues, the conflict could accelerate the long-term transition towards renewable energy sources and reshape how nations approach energy security.

Electricity is civilization": Winter looms over Ukraine battlefront

Ukraine Power Grid Restoration accelerates across liberated Kharkiv, restoring electricity, heat, and water amid missile and drone strikes, demining operations, blackouts, and winterization efforts, showcasing resilience, emergency repairs, and critical infrastructure recovery.

 

Key Points

Ukraine's rapid push to repair war-damaged grids, restore heat and water, and stabilize key services before winter.

✅ Priority repairs restore electricity and water in liberated Kharkiv.

✅ Crews de-mine lines and work under shelling, drones, and missiles.

✅ Winterization adds generators, mobile stoves, and large firewood supplies.

 

On the freshly liberated battlefields of northeast Ukraine, a pile of smashed glass windows outside one Soviet-era block of apartments attests to the violence of six months of Russian occupation, and of Ukraine’s sweeping recent military advances.

Indoors, in cramped apartments, residents lived in the dark for weeks on end.

Now, with a hard winter looming, they marvel at the speed and urgency with which Ukrainian officials have restored another key ingredient to their survival: electric power, a critical effort to keep the lights on this winter across communities.

Among those things governments strive to provide are security, opportunity, and minimal comfort. With winter approaching, and Russia targeting Ukraine’s infrastructure, add to that list heat and light, even as Russia hammers power plants nationwide. It’s requiring a concerted effort.

“Thank God it works! Electricity is civilization – it is everything,” says Antonina Krasnokutska, a retired medical worker, looking affectionately at the lightbulb that came on the day before, and now burns again in her tiny spotless kitchen.

“Without electricity there is no TV, no news, no clothes washing, no charging the phone,” says Ms. Krasnokutska, her gray hair pulled back and a small crucifix around her neck.

“Before, it was like living in the Stone Age,” says her grown son, Serhii Krasnokutskyi, who is more than a head taller. “As soon as it got dark, everyone would go to sleep.”

He shows a picture on his phone from a few days earlier, of a tangle of phone and computer charging cables – including his – plugged in at a local shop with a generator.

“We are very grateful for the people who repaired this electricity, even with shelling continuing,” he says. “They have a very complicated job.”

Indeed, although a lack of power might have been a novel inconvenience during the warm summer season, it increasingly has become a matter of great urgency for Ukrainian citizens and officials.

Coping through Ukraine’s winter with dignity and any degree of security will require courage and perseverance, as the severity and suffering that the season can bring here are being weaponized by Russia, as it seeks to compensate for a string of battlefield losses.

In recent days, Russian attacks have specifically targeted Ukraine’s electrical and other civilian infrastructure – all with the apparent aim of making this winter as hard as possible for Ukrainians, even as Moscow employs other measures to spread the hardship across Europe, while Ukraine helps Spain amid blackouts through grid support.

Ukrainian President Volodymyr Zelenskyy said Monday that Russian barrages across the country with missiles and Iran-supplied kamikaze drones had destroyed 30% of Ukraine’s power stations in the previous eight days, including strikes on western Ukraine that caused outages. Thousands of towns have been left without electricity.

Kharkiv’s challenges
Emblematic of the national challenge is the one facing officials in the northeast Kharkiv region, where Ukraine recaptured more than 3,000 square miles in a September counteroffensive. Ukrainian forces are still making gains on that front, as well as in the south toward Kherson, where Wednesday Russia started evacuating civilians from the first major city it occupied, after launching its three-pronged invasion last February.

Across the Kharkiv region, Ukrainians are stockpiling as much wood, fuel, and food as possible while they still can, and adopting new energy solutions as they prepare, from sources as diverse as the floorboards of destroyed schools and the pine forests in Izium, which are pockmarked with abandoned Russian trenches adjacent to a mass burial site.

“Of course, we have this race against time,” says Serhii Mahdysyuk, the Kharkiv regional director in charge of housing, services, fuel, and energy. “Unfortunately, we probably stand in front of the biggest challenge in Ukraine.”

That is not only because of the scale of liberated territory, he says, but also because the Kharkiv region shares a long border with Russia, as well as with the Russian-controlled areas of the eastern Donbas.

“It’s a great mixture of all threats, and we are sure that shelling and bombings will continue, but we are ready for this,” says Mr. Mahdysyuk. “We know our weak spots that Russia can destroy, but we are prepared for what to do in these situations.”

Ukraine’s battlefield gains have meant a surging need to pick up the pieces after Russian occupation, even as electricity reserves are holding if no new strikes occur, to ensure habitable conditions as more and more surviving residents require services, and as others return to scenes of devastation.

Restoring electricity is the top priority, amid shifting international assistance such as the end of U.S. grid support, because that often restarts running water, too, says Mr. Mahdysyuk. But before that, the area beneath broken power lines must be de-mined.

Indeed, members of an electricity team reconnecting cables on the outskirts of Balakliia – one of the first towns to see power restored, at the end of September – say they lost two fellow workers in the previous two weeks. One died after stepping on an anti-personnel mine, another when his vehicle hit an anti-tank device.

Ukrainian electricity workers restore power lines damaged during six months of Russian military occupation in Balakliia, Ukraine, Sept. 29, 2022. Ukrainians in liberated territory say the restoration of the electrical grid, and with it often the water supply, is a return to civilization.
“For now, our biggest problem is mines,” says the team leader, who gave the name Andrii. “It’s fine within the cities, but in the fields it’s a disaster because it’s very difficult to see them. There is a lot of [them] around here – it will take years and years to get rid of.”

Yet officials only have a few weeks to execute plans to provide for hundreds of thousands of residents in this region, in their various states of need and distress. Some 50 field kitchens capable of feeding 200 to 300 people each have been ordered. Another 1,000 mobile stoves are on their way.

And authorities will provide nearly 200,000 cubic yards of firewood for those who have no access to it, and may have no other means of keeping warm – or where shelling continues to disrupt repairs, says Mr. Mahdysyuk.

“The level of opportunity and resources we have is not the same as the level of destruction,” he says. People in districts and buildings too destroyed to have services restored soon, such as in Saltivka in Kharkiv city, may be moved.

Ottawa won't oppose halt to Site C work pending treaty rights challenge

Site C Dam Injunction signals Ottawa's neutrality while B.C. reviews a hydroelectric dam project on the Peace River, amid First Nations treaty rights claims, federal approval defenses, and scrutiny of environmental assessment and Crown consultation.

 

Key Points

A legal request to pause Site C while courts weigh First Nations treaty rights, environmental review, and approvals.

✅ Ottawa neutral on injunction; still defends federal approvals

✅ First Nations cite treaty rights over Peace River territory

✅ B.C. jurisdiction, environmental assessment and Crown consultation at issue

 

The federal government is not going to argue against halting construction of the controversial Site C hydroelectric dam in British Columbia while a B.C. court decides if the project violates constitutionally protected treaty rights.

 

Work on Site C suspended prior to First Nations lawsuit

However a spokeswoman for Environment Minister Catherine McKenna said Monday the government will continue to defend the federal approval given for the project in December 2014, even though that approval was given using an environmental review process McKenna herself has said is fundamentally flawed.

The Site C project is an 1,100-megawatt dam and generating station on the Peace River in northern B.C. that will flood parts of the traditional territory of the West Moberly and Prophet River First Nations.

#google#

In January, they filed a civil court case against the provincial government, B.C. Hydro and the federal government asking a judge to decide if their rights were being violated by the dam. A few weeks later, West Moberly asked the court for an injunction to halt construction pending the outcome of the rights case, similar to other contested transmission projects like the Maine electricity corridor debate in New England.

On May 11, lawyers for Attorney General Jody Wilson-Raybould filed a notice that Canada would remain neutral on the question of the injunction, meaning Canada won't argue against the idea of postponing construction for months, if not years, while the rights case winds through the court.

Wilson-Raybould has been silent on Site C since being named Canada's minister of justice in 2015, but in 2012, when she was the B.C. regional chief for the Assembly of First Nations, she said the project was "running roughshod" over treaty rights. The Justice Department on Monday directed questions to Environment and Climate Change Canada.

 

Defence of environmental assessment

McKenna's spokeswoman, Caroline Theriault, said the injunction request is just a procedural step regarding construction and that it is B.C. jurisdiction not federal.

However, she said Canada will defend the environmental assessment and Crown consultation processes and the federally issued permits required for construction.

 

B.C. auditor general set to scrutinize Site C dam project

McKenna has legislation before the House of Commons to overhaul the process for environmental assessment of major projects like hydro dams and pipelines, arguing the former government's procedures had skewed too far towards proponents. The overhaul includes requiring traditional Indigenous knowledge be taken into account, a consideration also central to the Columbia River Treaty talks underway on both sides of the border.

However, Theriault said the commitment to overhaul the process also included a promise not to revisit projects that had already been approved, such as Site C.

"The federal environmental assessment process for the Site C project has already been upheld in other court actions," said Theriault.

 

'It feels kind of odd'

West Moberly Chief Roland Wilson said he was both excited and yet concerned by Canada's decision last week not to oppose the injunction.

"It feels kind of odd and makes me wonder what they're up to," Wilson said.

However he said all he has ever wanted was for the project to be stopped until the question of rights can be answered. Wilson said two previous dams on the Peace River already flooded 80 per cent of the functional land within West Moberly's territory and that Site C will flood half of what's left. That land is used for fishing and hunting and there is also concern the dam will allow mercury to leak into Moberly Lake, he said.

 

Retiree undaunted by steep odds against his petition to stop Site C dam

Construction began in 2015 and more than $2.4 billion has already been spent on a project that will at the earliest, not be completed until 2024 and will cost an estimated $10 billion total, with cost overrun risks underscored by the Muskrat Falls ratepayer agreement in Atlantic Canada.

The province continues to argue against the injunction and will also fight the rights case, even as Alberta suspends power purchase talks with B.C. over energy disputes. Premier John Horgan campaigned on a promise to review the Site C approval. A B.C. Utilities Commission report in November found there are alternatives to building it and that it will go over budget. Nevertheless Horgan in December said he had to let construction continue because cancelling the project would be too costly both for the province and its electricity consumers, despite the B.C. rate freeze announced around the same period.

Florida says no to $400M in federal solar energy incentives

Florida Solar for All Opt-Out highlights Gov. DeSantis rejecting EPA grant funds under the Inflation Reduction Act, limiting low-income households' access to solar panels, clean energy programs, and promised electricity savings across disadvantaged communities.

 

Key Points

Florida Solar for All Opt-Out is the state declining EPA grants, restricting low-income access to solar energy savings.

✅ EPA grant under IRA aimed at low-income solar

✅ Estimated 20% electricity bill savings missed

✅ Florida lacks PPAs and renewable standards

 

Florida has passed up on up to $400 million in federal money that would have helped low-income households install solar panels.

A $7 billion grant “competition” to promote clean energy in disadvantaged communities by providing low-income households with access to affordable solar energy was introduced by President Joe Biden earlier this year, and despite his climate law's mixed results in practice, none of that money will reach Florida households.

The Environmental Protection Agency announced the competition in June as part of Biden’s Inflation Reduction Act. However, Florida Gov. Ron DeSantis has decided to pass on the $400 million up for grabs by choosing to opt out of the opportunity.

Inflation Reduction Act:What is the Inflation Reduction Act? Everything to know about one of Biden's big laws

The program would have helped Florida households reduce their electricity costs by a minimum of 20% during a key time when Floridians are leaving in droves due to a rising cost of living associated with soaring insurance costs, inflation, and proposed FPL rate hikes statewide.

Florida was one of six other states that chose not to apply for the money.

President Joe Biden announced a $7 billion “competition” to promote clean energy in disadvantaged communities.

The opportunity, named “Solar for All,” was announced by the EPA in June and promised to provide up to $7 billion in grants to states, territories, tribal governments, municipalities, and nonprofits to expand the number of low-income and disadvantaged communities primed for residential solar investment — enabling millions of low-income households to access affordable, resilient and clean solar energy.

The grant is intended to help lower energy costs for families, create jobs and help reduce greenhouse effects that accelerate global climate change by providing financial support and incentives to communities that were previously locked out of investments.


How much money would Floridians save under the ‘Solar for All’ solar panel grant?

The program aims to reduce household electricity costs by at least 20%. Florida households paid an average of $154.51 per month for electricity in 2022, just over 14% of the national average of $135.25, and debates over hurricane rate surcharges continue to shape customer bills, according to the U.S. Energy Information Administration. A 20% savings would drop those bills down to around $123 per month.

On the campaign trail, DeSantis has pledged to unravel Biden’s green energy agenda if elected president, amid escalating solar policy battles nationwide, slamming the Inflation Reduction Act and what he called “a concerted effort to ramp up the fear when it comes to things like global warming and climate change.”

His energy agenda includes ending Biden’s subsidies for electric cars while pushing policies that he says would ramp up domestic oil production.

“The subsidies are going to drive inflation higher,” DeSantis said at an event in September. “It’s not going to help with interest rates, and it is certainly not going to help with our unsustainable debt levels.”

DeSantis heading to third debate:As he enters third debate, Ron DeSantis has a big Nikki Haley problem

DeSantis’ plan to curb clean energy usage in Florida seems to be at odds with the state as a whole, and the region's evolving strategy for the South underscores why it has been ranked among the top three states to go solar since 2019, according to the Solar Energy Industries Association (SEIA).

SEIA also shows, however, that Florida lags behind many other states when it comes to solar policies, as utilities tilt the solar market in ways that influence policy outcomes statewide. Florida, for instance, has no renewable energy standards, which are used to increase the use of renewable energy sources for electricity by requiring or encouraging suppliers to provide customers with a stated minimum share of electricity from eligible renewable resources, according to the EIA.

Power purchase agreements, which can help lower the cost of going solar through third-party financing, are also not allowed in Florida, with court rulings on monopolies reinforcing the existing market structure. And there have been other policies implemented that drove other potential solar investments to other states.

7 steps to make electricity systems more resilient to climate risks

Electricity System Climate Resilience underpins grid reliability amid heatwaves and drought, integrating solar, wind, hydropower, nuclear, storage, and demand response with efficient transmission, flexibility, and planning to secure power for homes, industry, and services.

 

Key Points

Power systems capacity to endure extreme weather and integrate clean energy, maintaining reliability and flexibility.

✅ Grid hardening, transmission upgrades, and digital forecasting.

✅ Flexible low-carbon supply: hydropower, nuclear, storage.

✅ Demand response, efficient cooling, and regional integration.

 

Summer is just half done in the northern hemisphere and yet we are already seeing electricity systems around the world struggling to cope with the severe strain of heatwaves and low rainfall.

These challenges highlight the urgent need for strong and well-planned policies and investments to improve the security of our electricity systems, which supply power to homes, offices, factories, hospitals, schools and other fundamental parts of our economies and societies. This means making our electricity systems more resilient to the effects of global warming – and more efficient and flexible as they incorporate rising levels of solar and wind power, as solar is now the cheapest electricity in history according to the IEA, which will be critical for reaching net-zero emissions in time to prevent even worse impacts from climate change.

A range of different countries, including the US, Canada and Iraq, have been hard hit by extreme weather recently in the form of unusually high temperatures. In North America, the heat soared to record levels in the Pacific Northwest. An electricity watchdog says that five US regions face elevated risks to the security of their electricity supplies this summer, underscoring US grid climate risks that could worsen, and that California’s risk level is even higher.

Heatwaves put pressure on electricity systems in multiple ways. They increase demand as people turn up air conditioning, driving higher US electricity bills for many households, and as some appliances work harder to maintain cool temperatures. At the same time, higher temperatures can also squeeze electricity supplies by reducing the efficiency and capacity of traditional thermal power plants, such as coal, natural gas and nuclear. Extreme heat can reduce the availability of water for cooling plants or transporting fuel, forcing operators to reduce their output. In some cases, it can result in power plants having to shut down, increasing the risk of outages. If the heat wave is spread over a wide geographic area, it also reduces the scope for one region to draw on spare capacity from its neighbours, since they have to devote their available resources to meeting local demand.

A recent heatwave in Texas forced the grid operator to call for customers to raise their thermostats’ temperatures to conserve energy. Power generating companies suffered outages at much higher rates than expected, providing an unwelcome reminder of February’s brutal cold snap when outages – primarily from natural gas power plants – left up to 5 million customers across the US without power over a period of four days.

At the same time, lower than average rainfall and prolonged dry weather conditions are raising concerns about hydropower’s electricity output in various parts of the world, including Brazil, China, India and North America. The risks that climate change brings in the form of droughts adds to the challenges faced by hydropower, the world’s largest source of clean electricity, highlighting the importance of developing hydropower resources sustainably and ensuring projects are climate resilient.

The recent spate of heatwaves and unusually long dry spells are fresh warnings of what lies ahead as our climate continues to heat up: an increase in the scale and frequency of extreme weather events, which will cause greater impacts and strains on our energy infrastructure.

Heatwaves will increase the challenge of meeting electricity demand while also decarbonizing the electricity supply. Today, the amount of energy used for cooling spaces – such as homes, shops, offices and factories – is responsible for around 1 billion tonnes of global CO2 emissions. In particular, energy for cooling can have a major impact on peak periods of electricity demand, intensifying the stress on the system. Since the energy demand used for air conditioners worldwide could triple by 2050, these strains are set to grow unless governments introduce stronger policy measures to improve the energy efficiency of air conditioning units.

Electricity security is crucial for smooth energy transitions
Many countries around the world have announced ambitious targets for reaching net-zero emissions by the middle of this century and are seeking to step up their clean energy transitions. The IEA’s recent Global Roadmap to Net Zero by 2050 makes it clear that achieving this formidable goal will require much more electricity, much cleaner electricity and for that electricity to be used in far more parts of our economies than it is today. This means electricity reaching much deeper into sectors such as transport (e.g. EVs), buildings (e.g. heat-pumps) and industry (e.g. electric-arc steel furnaces), and in countries like New Zealand's electrification plans it is accelerating broader efforts. As clean electricity’s role in the economy expands and that of fossil fuels declines, secure supplies of electricity become ever-more important. This is why the climate resilience of the electricity sector must be a top priority in governments’ policy agendas.

Changing climate patterns and more frequent extreme weather events can hit all types of power generation sources. Hydropower resources typically suffer in hot and dry conditions, but so do nuclear and fossil fuel power plants. These sources currently help ensure electricity systems have the flexibility and capacity to integrate rising shares of solar and wind power, whose output can vary depending on the weather and the time of day or year.

As governments and utilities pursue the decarbonization of electricity systems, mainly through growing levels of solar and wind, and carbon-free electricity options, they need to ensure they have sufficiently robust and diverse sources of flexibility to ensure secure supplies, including in the event of extreme weather events. This means that the possible decommissioning of existing power generation assets requires careful assessments that take into account the importance of climate resilience.

Ensuring electricity security requires long-term planning and stronger policy action and investment
The IEA is committed to helping governments make well-informed decisions as they seek to build a clean and secure energy future. With this in mind, here are seven areas for action for ensuring electricity systems are as resilient as possible to climate risks:

1. Invest in electricity grids to make them more resilient to extreme weather. Spending today is far below the levels needed to double the investment for cleaner, more electrified energy systems, particularly in emerging and developing economies. Economic recovery plans from the COVID-19 crisis offer clear opportunities for economies that have the resources to invest in enhancing grid infrastructure, but much greater international efforts are required to mobilize and channel the necessary spending in emerging and developing economies.

2. Improve the efficiency of cooling equipment. Cost-effective technology already exists in most markets to double or triple the efficiency of cooling equipment. Investing in higher efficiency could halve future energy demand and reduce investment and operating costs by $3 trillion between now and 2050. In advance of COP26, the Super-Efficient Equipment and Appliance Deployment (SEAD) initiative is encouraging countries to sign up to double the energy efficiency of equipment sold in their countries by 2030.

3. Enable the growth of flexible low-carbon power sources to support more solar and wind. These electricity generation sources include hydropower and nuclear, for countries who see a role for one or both of them in their energy transitions. Guaranteeing hydropower resilience in a warming climate will require sophisticated methods and tools – such as the ones implemented in Brazil – to calculate the necessary level of reserves and optimize management of reservoirs and hydropower output even in exceptional conditions. Batteries and other forms of storage, combined with solar or wind, can also provide important amounts of flexibility by storing power and releasing it when needed.

4. Increase other sources of electricity system flexibility. Demand-response and digital technologies can play an important role. The IEA estimates that only a small fraction of the huge potential for demand response in the buildings sector is actually tapped at the moment. New policies, which associate digitalization and financial behavioural incentives, could unlock more flexibility. Regional integration of electricity systems across national borders can also increase access to flexible resources.

5. Expedite the development and deployment of new technologies for managing extreme weather threats. The capabilities of electricity utilities in forecasting and situation awareness should be enhanced with the support of the latest information and communication technologies.

6. Make climate resilience a central part of policy-making and system planning. The interconnected nature of recent extreme weather events reminds us that we need to account for many contingencies when planning resilient power systems. Climate resilience should be integral to policy-making by governments and power system planning by utilities and relevant industries, and debates over Canadian climate policy underscore how grid implications must be considered. According to the recent IEA report on climate resilience, only nine out of 38 IEA member and association countries include concrete actions on climate adaptation and resilience for every segment of electricity systems.

7. Strengthen international cooperation on electricity security. Electricity underpins vital services and basic needs, such as health systems, water supplies and other energy industries. Maintaining a secure electricity supply is thus of critical importance. The costs of doing nothing in the face of growing climate threats are becoming abundantly clear. The IEA is working with all countries in the IEA family, as well as others around the world, by providing unrivalled data, analysis and policy advice on electricity security issues. It is also bringing governments together at various levels to share experiences and best practices, and identify how to hasten the shift to cleaner and more resilient energy systems.
